INIPROVEMET IN WATER-ELEVATORS.

The Schedule referred to Ln these Letters Patentand making part of thesame.

To all whom it may concern:

Be it known `that I, DAVID JONES, of Machen Newport, Wales, nowtemporarily residing in thev city, county, and State of New York, haveinvented a new and improved Mode of Raising Water; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to makeand use thesame, reference being had to the. accompanying drawings, forming part ofthis specification.

This invention relates to new and important improvements in the methodof raising water through a vacuum produced by the condensation of steam;and

It consists informing a vacuum by means of a tlexible bag, which isinflated by steam, which steam is condensed or allowed to escape.

And it also consists in measuring the steam which is discharged into theexpansible and collapsible bag,

,thereby preventing undue pressure therein, as will be hereinafter morefully described.

The accompanying drawing represents an elevation of the machine,thevacuum-chamber and flexible bag being shown in section, and portionsol' the supplytube being broken away, in order to show to betteradvantage the nature and operation of the device.

A is the cistern or fountain.

B is the vacuum-chamber, into which vthe water is raised, and whichcontains the flexible bag.

C represents the bagfwhich is made of rubber, or other flexiblewater-proof material.

D is the supply-pipe.

' This pipe is connected with the chamber B, as seen in the drawing.

It has a check-valve at its bottom end for preventing the return ofthewater, as seen at e.

F is the discharge-pipe.

G represents a steam-boiler, for generating the requisite quantity ofsteam.

H is a measuring-vessel, from which the steam is expanded into the bag.

I isthe steam-pipe, which conducts steam from the boiler to the vesselH, and from thence to the collapsible bag G.

J is a pipe, by which the steam is discharged from the bag into acondenser, K, which is connected with the cistern A by the pipe L. n

It will be seen that there are two pairs of cocks, which are operated byrods, the cocks of each pair being connected together, so that they maybe opened and closed simultaneously; the cock m, in the discharge-pipeF, and the cock n, in the steam-pipe I, being one pair, connected by therod o, and the cock p, in the steam-pipe I, and the cock q, inthesteamdischarge pipe J, connected by the rod r, being the other pair.

When one pair of these cocks is open, the other pair is closed, and cioeversa.

Steam being discharged into the vessel H, will fill it atboiler-pressure, but the quantity is designed to be sosmall thatwhen itis expanded into the tlexible bag C,'it will expand only sufficiently toinflate the bag, and force out any air and water that may be con-` Thebag O will collapse, and a vacuum will be-`r formed, more or lesscomplete, ln the chamber B,

when the water will rise through the pipe D to till it. The bag is againfilled or inflated as before, and the operation is repeated as long asmay be desired.

The advantages of this arrangement are, that by measuring the steamthrough the vessel H, and 'expanding it therefrom, high steam is notallowed to enter the bag, consequently there can be no injuriouspressure on the bag; and as the steam does not come iu contact with thesides of the chamber B, the condensation is slight, and the amount ofsteam to work the machine is very small.

Steam maybe taken from any source, as from a stationary boiler in anyother situation, or fromA a locomotive, when taking in a supply of waterat arailroad station.

I claim as new, anddesire to secure by Letters Patent- 1. In a devicefor raising wat-er by a 'vacuum formed by the condensation of steam, theexpansible bag O, in combination with the air and Water-tight chamber B,substantially as described, for the purpose specified.

2. rIhe steam-measuring vesselH, in combination with an arrangement ofdevices for raising water by a vacuum formed by the condensation ofsteam, or by the discharge of steam, substantially as described, for thepurpose specified.

The above specification of my invention signed by me, this 18th day ofDecember, 1868;

. DAVID JONES.
